Definitions
- This disclosure relates generally to a service disconnect and, more particularly, to an indicator for verifying a position of the service disconnect.
- electric vehicles differ from conventional motor vehicles because electric vehicles are selectively driven using one or more battery-powered electric machines.
- Conventional motor vehicles by contrast, rely exclusively on an internal combustion engine to drive the vehicle. Electric vehicles may use electric machines instead of, or in addition to, the internal combustion engine.
- Example electric vehicles include hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), fuel cell vehicles, and battery electric vehicles (BEVs).
- a powertrain of an electric vehicle is typically equipped with a battery that stores electrical power for powering the electric machine.
- the battery may be charged prior to use.
- the battery may be recharged during a drive by regeneration braking or an internal combustion engine.
- Electric vehicles include service disconnects.
- the service disconnect is seated closed. Opening the service disconnect may be necessary when, for example, performing maintenance on the electric vehicle. Verifying that the service disconnect is seated and closed can be difficult.
- the service disconnect may be appear closed, but not be seated. In such examples, road vibration for example, can undesirably cause the service disconnect to open.
- a method of verifying that a service disconnect is seated includes, among other things, indicating that the service disconnect is seated using a position indicator that selectively engages a handle of the service disconnect.
- the position indicator is separate and distinct from all portions of the service disconnect.
- Another example of the foregoing method includes blocking the position indicator from engaging the service disconnect unless the service disconnect is in a seated position.
- Another example of the foregoing method includes pivoting and then sliding the handle of the service disconnect relative to a base of the service disconnect to transition the service disconnect from an unseated position to a seated position.
- the handle moves along an axis when sliding relative to the base to transition the service disconnect from the unseated position to the seated position.
- Another example of the foregoing method includes a first and a second clip positioned adjacent opposing axial ends of the handle.
- the first and second clips engage the handle such that the entire handle is axially disposed between the first and the second clips when the position indicator is in an engaged position with the service disconnect.
- the position indicator is moveable from a disengaged to an engaged position when the service disconnect in the seated position, and is not moveable to the engaged position when the service disconnect is in the unseated position.
- a first clip and a second clip of the position indicator engage a perimeter of the handle to hold the position indicator in the engaged position.
- the first clip of the position indicator engages a surface of the service disconnect facing away from a base of the position indicator when the service disconnect is in the seated position.
- a service disconnect seating verification method includes, among other things, transitioning a service disconnect from an unseated to a seated position by pivoting and then sliding a handle of a service disconnect relative to a base of the service disconnect, and securing a position indicator to opposing axial ends of the handle when the service disconnect is in the seated position. The securing is blocked when the service disconnect is in the unseated position.
- the position indicator is separate and distinct from all portions of the service disconnect.
- the securing comprises clipping a first clip and a second clip to a perimeter of the handle.
- the sliding is along an axis
- the securing comprises clipping a first clip to an first axial end of the handle, and a second clip to an opposite second axial end of the handle.
- the first clip extends from a position indicator base.
- the first clip contacts a first surface of the service disconnect facing away from the position indicator base when the service disconnect is in the seated position and the position indicator is in the engaged position with the service disconnect.
- the first clip is prevented from contacting the first surface by a second surface of the service disconnect facing toward the position indicator base when the service disconnect is in the unseated position.
- the first surface is a surface of the handle of the service disconnect.
- the first clip rotates about the second clip during the clipping.
- the entire handle is axially disposed between the first clip and the second clip when the position indicator is in the engaged position.
- the service disconnect is opened to electrically disconnect portions of an electric vehicle powertrain and closed to electrically connect the portions of the electric vehicle powertrain.
- a plurality of high voltage contactors of an electric vehicle powertrain are connected when the service disconnect is closed, and the plurality of high voltage contactors of the electric vehicle powertrain are disconnected when the service disconnect is open.

- FIG. 1 schematically illustrates a powertrain 10 for an electric vehicle.
- HEV hybrid electric vehicle
- PHEVs plug-in hybrid electric vehicles
- BEVs battery electric vehicles
- the powertrain 10 is a powersplit powertrain system that employs a first drive system and a second drive system.
- the first drive system includes a combination of an engine 14 and a generator 18 (i.e., a first electric machine).
- the second drive system includes at least a motor 22 (i.e., a second electric machine), the generator 18 , and a battery 24 .
- the second drive system is considered an electric drive system of the powertrain 10 .
- the first and second drive systems generate torque to drive one or more sets of vehicle drive wheels 28 of the electric vehicle.
- the engine 14 which is an internal combustion engine in this example, and the generator 18 may be connected through a power transfer unit 30 , such as a planetary gear set.
- a power transfer unit 30 such as a planetary gear set.
- the power transfer unit 30 is a planetary gear set that includes a ring gear 32 , a sun gear 34 , and a carrier assembly 36 .
- the generator 18 can be driven by engine 14 through the power transfer unit 30 to convert kinetic energy to electrical energy.
- the generator 18 can alternatively function as a motor to convert electrical energy into kinetic energy, thereby outputting torque to a shaft 38 connected to the power transfer unit 30 . Because the generator 18 is operatively connected to the engine 14 , the speed of the engine 14 can be controlled by the generator 18 .
- the ring gear 32 of the power transfer unit 30 may be connected to a shaft 40 , which is connected to vehicle drive wheels 28 through a second power transfer unit 44 .
- the second power transfer unit 44 may include a gear set having a plurality of gears 46 .
- Other power transfer units may also be suitable.
- the gears 46 transfer torque from the engine 14 to a differential 48 to ultimately provide traction to the vehicle drive wheels 28 .
- the differential 48 may include a plurality of gears that enable the transfer of torque to the vehicle drive wheels 28 .
- the second power transfer unit 44 is mechanically coupled to an axle 50 through the differential 48 to distribute torque to the vehicle drive wheels 28 .
- the motor 22 (i.e., the second electric machine) can also be employed to drive the vehicle drive wheels 28 by outputting torque to a shaft 52 that is also connected to the second power transfer unit 44 .
- the motor 22 and the generator 18 cooperate as part of a regenerative braking system in which both the motor 22 and the generator 18 can be employed as motors to output torque.
- the motor 22 and the generator 18 can each output electrical power to the battery 24 .
- the battery 24 is an example type of electric vehicle battery assembly.
- the battery 24 may have the form of a high voltage battery that is capable of outputting electrical power to operate the motor 22 and the generator 18 .
- Other types of energy storage devices and/or output devices can also be used with the electric vehicle having the powertrain 10 .
- a service disconnect 56 is used to selectively disconnect the battery 24 from other portions of the powertrain 10 .
- the service disconnect 56 may be located in various positions within the vehicle, including areas near the battery 24 . In other examples, the service disconnect 56 may be used to electrically disconnect other areas of the powertrain 10 .
- the service disconnect 56 can be closed or open. When closed, the battery 24 is electrically connected to the remaining portions of the powertrain 10 . When open, the battery 24 is electrically disconnected from the remaining portions of the powertrain 10 . When the service disconnect 56 is closed, a high voltage interlock loop and high voltage contactors of the powertrain 10 are closed. When the service disconnect 56 is open, the high voltage interlock loop and the high voltage contactors are open. In some examples, the service disconnect 56 transitioning from closed to open triggers an alert, such as an on-board diagnostic code that is displayed within the vehicle.
- the service disconnect 56 is seated within the powertrain 10 when closed. Unseating the service disconnect 56 then causes the service disconnect 56 to open.
- the service disconnect 56 When the powertrain 10 is assembled, the service disconnect 56 should be seated within the powertrain 10 on the assembly line. Seating the service disconnect 56 ensures the service disconnect 56 remains closed, during operation of the powertrain 10 . Seating the service disconnect 56 prevents the service disconnect 56 from undesirably moving from closed to open.
- a technician may unseat the service disconnect 56 and move the service disconnect from closed to open.
- seating the service disconnect 56 is not required for the service disconnect 56 to close.
- the service disconnect 56 may undesirably slide or otherwise move from closed to open when such movement is not desired, such as when the vehicle is moving. That is, when the service disconnect 56 is seated, the service disconnect 56 does not move from the closed to open when such movement is not desired.
- the service disconnect 56 may move from the closed to open when such movement is not desired.
- the example powertrain 10 includes a position indicator 60 used to verify that the service disconnect 56 is seated.
- the example service disconnect 56 includes a handle 64 , or cam lever, that is pivotably attached to a base 68 to move the service disconnect 56 from unseated and open ( FIG. 2 ) to seated and closed ( FIG. 5 ).
- moving the service disconnect 56 to a seated and closed position includes pivoting the handle 64 in a direction P relative to the base 68 until the handle 64 is in the position of FIG. 4 .
- the handle 64 slides in a direction D from the position shown in FIG. 4 to the seated position of FIG. 5 .
- the service disconnect 56 may be closed when the service disconnect 56 is in the position of, for example, FIG. 4 , the service disconnect 56 is not closed and seated until the service disconnect 56 is in the position of FIG. 5 .
- the service disconnect 56 may undesirably move from closed to open.
- Seating the service disconnect 56 as shown in FIG. 5 , prevents undesirably movement from closed to open.
- a position indicator 60 is configured to engage with the service disconnect 56 when the service disconnect 56 is seated as shown in FIG. 5 .
- the example position indicator 60 cannot be properly secured onto, or engaged with, the service disconnect 56 .
- the example position indicator 60 grabs a perimeter of the handle 64 when secured onto the service disconnect 56 .
- the position indicator 60 secured to the service disconnect 56 confirms that the service disconnect 56 is seated rather than, for example, in the position of FIG. 4 .
- the position indicator 60 and the service disconnect 56 may be made of contrasting colors to facilitate identifying the position indicator 60 is secured to the service disconnect.
- the position indicator 60 and the service disconnect 56 together provide a service disconnect assembly.
- the position indicator 60 includes a first clip 72 , a second clip 76 , and an installation tab 80 extending from a base 84 .
- the second clip 76 is positioned under a lip 88 of the service disconnect 56 .
- the position indicator 60 is then rotated in the direction P such that the first clip 72 is rotated about the second clip 76 and toward a position engaged with the handle 64 .
- the tab 80 extends from the base opposite the first clip 72 .
- a user may grasp the tab 80 to rotate the position indicator 60 .
- the first clip 72 will contact a surface 92 of the handle 64 as shown in FIG. 7 . If the service disconnect 56 is in the seated position of FIGS. 5 and 6 , a groove 96 of the first clip 72 will receive a pin 100 extending from the hinged handle 64 .
- the position indicator 60 comprises a polyvinyltoluene material to facilitate some flexing of the first clip 72 during assembly.
- the example position indicator 60 For the pin 100 to be received within the groove 96 and the second clip 76 to be received behind the lip 88 , the example position indicator 60 must be seated.
- the position indicator 60 is thus only installable when the service disconnect 56 is in the seated position. If the service disconnect 56 is not in the seated position, the position indicator 60 cannot be secured, and may fall off the service disconnect 56 .
- the position indicator 60 that is not secured to the service disconnect 56 provides a visual indication that the service disconnect 56 is not seated.
- the example position indicator 60 includes alignment ribs 104 for engaging opposing sides of the service disconnect 56 .
- the position indicator 60 may include a window 108 to reveal information about the service disconnect 56 , such as text information stamped into the service disconnect 56 .
- Support ribs 112 extend from the base 84 of the service disconnect 56 to the tab 80 .
- Support ribs 116 also extend from the base 84 to the second clip 76 .
- another example position indicator 60 A may include two first clips 72 ′ spaced from each other.
- the two first clips 72 ′ engage a surface 120 of the service disconnect opposite a base 84 ′ of the position indicator 60 ′.
- the position indicator 60 A can engage the service disconnect 56 only when the service disconnect 56 is seated.
